The DX140LCR-5 Doosan crawler excavators has been added to the Tier 4-compliant line-up, featuring improved performance, operator-focused comfort, fuel economy and jobsite durability. The 14-metric-ton compliant machine replaces the interim Tier 4 “dash-3” models.
The DX140LCR-5 model offers a shorter tail swing, allowing operators greater flexibility where space is a premium without sacrificing performance while also being designed for long life with an extra-sturdy frame and reinforced superstructure. The Doosan DX140LCR-5 comes standard with permanently sealed and lubricated track links, and the bushings and hard-wear disks are designed for reliability as well as extended service intervals to increase uptime.
Smart Power Control (SPC)
A new selectable feature, Smart Power Control (SPC), is available on the DX140LCR-5 and consists of two systems — Variable Speed Control and Pump Torque Control — that work together to improve machine efficiency while maintaining productivity and reducing fuel consumption. The engine control unit (ECU) automatically manages SPC when SPC is engaged. Each of the four power modes will function with SPC engaged or disengaged; however, SPC can be active only in the Digging work mode.
- Variable Speed Control: Reduces engine rpm during low workload requirements such as during the swing portion of a dig cycle. This reduces the total energy required to perform a task and improves fuel efficiency by up to 3 to 7 percent.
- Pump Torque Control: Efficiently matches hydraulic pump torque and engine response to the task, preventing engine overload and excess fuel consumption, improving efficiency.
The DX140LCR-5 comes standard with an improved 7-inch liquid-crystal display (LCD) screen that allows operators to continue monitoring the excavator parameters while viewing the rearview or optional side-view camera image. Critical machine data appears next to the camera view. With an optional side camera, a split screen allows both camera displays to be viewed at once. New additions to the monitor include the diesel exhaust fluid (DEF) gauge and improved fuel efficiency.
To help save valuable diesel fuel, Doosan added auto shutdown to help owners save fuel during non-working conditions. Operators can configure the idle time from 3 to 60 minutes. When enabled, the feature will shut down the excavator’s engine when the preset idle time is met. This is particularly helpful in California where state regulations require idling for only 5 minutes for off-highway machines.
Tier 4 solution
The Doosan DX140LCR-5 complies with Tier 4 emission standards with modified diesel engines and after treatment technologies. The engine is optimized for use with a high-pressure common-rail (HPCR) fuel delivery system and a cooled exhaust gas recirculation (CEGR) system. It utilizes a diesel oxidation catalyst (DOC) to reduce particulate matter (PM) and selective catalyst reduction (SCR) after treatment to reduce nitrogen oxides (NOx). Additionally, a variety of after treatment systems have been implemented as part of the Tier 4 compliance, such as DEF, which is used with SCR technology.
